Hal, if you like Gunnys' idea of using the thin plane curls, I would modify that a bit and glue them with epoxy rather than Titebond. I'm assuming he missed the part about you having sealed the wood with superglue, and you won't be able to remove the superglue without removing even more wood. Titebond is very strong where it can penetrate the pores of wood, but not so good on a non-porous surface. Multiple layers of plane chips and epoxy may end up darker than you wish, so I'd go with a single over-size piece of closely matching wood and shave that down to the final fit you want.
